Applicant's summary and conclusion

Conclusions:
The chromatograms show one peak with an average retention time of 10.93 minutes, corresponding to a partition coefficient (log value) of 4.5.
Therefore :Partition coefficient n-octanol/water of TETRAHYDROCITRAL: log Pow = 4.5
Executive summary:

The Partition Coefficient n-octanol/water of TETRAHYDROCITRAL was determined by the Reverse Phase High Performance Liquid Chromatographic Method according to the OECD Guidelines for Testing of Chemicals, Method No. 117.

 

The result is:

Partition coefficient n-octanol/water of TETRAHYDROCITRAL:log Pow= 4.5
